3.1 Fan installation
Installation must be completed by qualified personnel. A solid non
reverberant mounting position must be selected and passages for
ductwork from the outlet spigot, as well as electrical connection
prepared. Compatible ductwork should have already been installed.
3.2 Required tools
Drill, PH2 Screwdriver, Terminal Screwdriver and Tape Measure.
3.3 Installation procedures
Fig 10. Surface mounted on a cavity wall.
1. Unpack the fan unit and other components, and ensure that all
parts listed on page 1 are present. If not please contact the
manufacturer for replacement / missing parts.
2.
Place the front cover and inlet grille to one side.
3.
Remove the PCB cover by removing 2 off No6 x
1
⁄
2
inch screws.
4.
Partially remove the PCB assembly from the fan casing by
placing a finger tip behind the dip switches and pulling the PCB
away from the fan casing. (see fig 11).
Fig 11. Removal of PCB cover from casing.
5.
Disconnect and remove the fan scroll from assembly and
completely remove the PCB assembly. Note: if the pull cord is
not required, remove it completely.
6.
Core cut a hole through mounting surface at desired mounting
position to suit the size of the discharge spigot required,
100mm or 125mm dia.
7.
Place the fan casing in the mounting position (spigot placed into
core cut hole) and use the base as a template to mark the
mounting screw hole positions (x3), remove casing once marks
are made.
8.
Drill and plug (if necessary) the mounting surface.
9.
Feed wiring flex through the back of the fan casing and secure
into place using cable clamps and screws provided in the CYFAN
fixing kit.
10. Secure the case to the surface (fixings supplied by others). Note:
care must be taken not to twist or distort the case whilst fitting.
Ensure the 3 spacers are used from the fixing kit (see fig 12).
11. Partually replace PCB into the fan casing and wire flex into the
terminal block (see wiring options on page 5).
Fig 12. Use cable clamp on rear of casing to secure wiring, and the 3
nylon spacers from the fixing kit to ensure the unit is not flush to the
wall. This will allow the power cable to run behind the unit.
12. Replace fan scroll assembly and plug motor into PCB, replace
PCB fully into position by pushing the dip switches.
13. Replace PCB cover by fitting with 2 off No6 x
1
⁄
2
inch screws.
(see point 2 of the procedure).
14. Fit front inlet grille using 4 off No6 x
3
⁄
4
inch screws found in
the fixing kit.
15. Remove rubber gasket and adjust control to required settings
(shown in section 4). Once required settings are complete and
desired airflow rate is achieved replace rubber gasket.
16. Complete the fan installation by fitting (push fit) the front cover.
